Age spots, also known as liver spots or sunspots, are flat, brown or black spots that appear on the skin as a result of aging and sun exposure. They most commonly occur on areas of the skin that are frequently exposed to the sun, such as the face, hands, shoulders, and arms.
Age spots are caused by an overproduction of melanin, which is the pigment that gives skin its color. Over time, sun exposure and the natural aging process can cause the melanin to clump together and form age spots. They are generally harmless and do not require treatment, although some people may choose to have them removed for cosmetic reasons.
It's important to note that while age spots are generally harmless, they can sometimes be a sign of skin cancer, so it's important to have any new or changing spots checked by a board-certified dermatologist.
